Step 1

Cook the whole-wheat pasta in boiling salted water, according to package directions.

Step 2

In a large frying pan, heat the olive oil over medium high heat. Add the onion and cook for 5 minutes, or until it begins to soften and brown. Add the chorizo and cook, stirring frequently, for 5 minutes, or until the chorizo is cooked and the onion is nicely browned. Add the chile flakes, garlic and kale and cook until the kale is just barely wilted, about 1 minute. Remove from heat.

Step 3

Add the cooked pasta to the pan and toss to coat well. Add more olive oil as necessary and generously season with sea salt and freshly ground pepper
